Toothbrush head



FIG. 1 is a front perspective view of the toothbrush head from above and one side;

FIG. 2 is a side view of the toothbrush head (other side corresponds);

FIG. 3 is a top plan view of the toothbrush head; and,

FIG. 4 is an underneath plan view of the toothbrush head.

The broken line shown at one end in each of the views defines the bounds of the claim but forms no part of the claimed design. 

I claim the ornamental design for a toothbrush head, as shown and described.
